Radiomaster Zorro ELRS 2.4GHz Radio Transmitter

The ExpressLRS version of a popular compact radio

The RadioMaster Zorro ELRS is a high-performance drone controller with ExpressLRS protocol support. It is a compact radio with an ergonomic design, adjustable Hall sensor gimbals and an oversized LCD screen that makes model setup and telemetry easy to read.

It works with both OpenTX and EdgeTX firmware, so it fits into the open source radio ecosystem that most FPV pilots already use, and it supports external TBS and ELRS modules if you want flexibility.

Everyday use

USB-C provides charging and data connection for updates and simulators, so the same cable that charges the radio also lets you fly a simulator or update firmware. Because it is designed as a compact radio, it is easy to carry and quick to set up on the field.

Start by creating a model, binding your ExpressLRS receiver with a matching binding phrase, and calibrating the gimbals. If you plan to use an external module, check that it is compatible with the module bay and set the module type in the radio's menu.

How it differs from the CC2500 version

This is the ELRS radio, meant for pilots whose receivers use ExpressLRS. The multi-protocol CC2500 version of the Zorro supports a wider range of older receivers instead, so pick the version that matches the receivers you own.

Getting it ready to fly

Charge the radio over USB-C, calibrate the Hall gimbals and adjust stick tension to suit you. Create your first model, set the internal or external module type, and bind your receiver with the binding phrase. Add a screen protector and a strap if you carry the radio around, since the compact body is easy to slip into a bag and the gimbals like protection.
